Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If for lab-grade variants of other aromatic carbodiimides
Unnamed aromatic imides, even lab-grade, fall under the broader 'other' category in this subheading.
If containing directly linked sulfur impurities
Chapter notes move organo-sulfur compounds to 2930 if sulfur is directly carbon-linked beyond imide function.

Bis(o-tolyl)carbodiimide
Bis(o-tolyl)carbodiimide is a specific aromatic imide-function compound used primarily as a dehydrating agent and coupling reagent in organic synthesis, particularly for peptide bond formation. It falls under HTS 2925.19.30.00 as one of the explicitly named aromatic imides, meeting Chapter 29 requirements for separate chemically defined organic compounds with imide functionality.
2,2',6,6'-Tetraisopropyldiphenylcarbodiimide (TIPC)
2,2',6,6'-Tetraisopropyldiphenylcarbodiimide, commonly known as TIPC, is a sterically hindered aromatic carbodiimide used as a coupling agent in peptide synthesis and polymer chemistry due to its stability. It is explicitly named in HTS 2925.19.30.00 as an aromatic imide derivative, qualifying under Chapter 29 for pure, chemically defined imine-function compounds.
Bis(o-tolyl)carbodiimide 98% Pure Technical Grade
This technical-grade Bis(o-tolyl)carbodiimide at 98% purity is supplied for industrial organic synthesis applications like amide coupling. It remains classified under HTS 2925.19.30.00 as the named aromatic imide, as minor impurities do not exclude it from Chapter 29's chemically defined compounds.
Bis(o-tolyl)carbodiimide with Stabilizer Additive
This form includes a stabilizer for transport stability, as permitted by Chapter 29 note (f), and is still classified as Bis(o-tolyl)carbodiimide under HTS 2925.19.30.00 since the addition is solely for preservation without specific use adaptation.
